Chronic groin pain in an amateur soccer player.

Chronic groin pain is common in soccer players because of the biomechanics of kicking causing recurrent stress to the abdominal muscles, groin flexors, and adductor muscles. Myositis ossificans in adductor muscles is a rare cause of chronic groin pain in soccer players. Only two cases have been reported and the iliopsoas muscle was involved in both. This case report emphasises the importance of direct radiography for diagnosis in chronic groin pain and is a reminder that the development of myositis ossificans in the adductor muscles may be a cause.
